- If a mineral occurs in a rainbow of colors, color would be a good characteristic to classify that mineral.
- The primary mineral that can be identified by its reaction to acid is calcite.
-Granite likely contains quartz and feldspar minerals.
- Quartz has a hardness of 7 on the Moh's Hardness Scale and it will scratch apatite and orthoclase.
Please explain why the statement is not true!
The option that is not a true statement about minerals is that the primary mineral that can be identified by its reaction to acid is calcite.
How to illustrate the information?It should be noted that minerals are the natural resources that can be found in the ground.

Answer:
The primary mineral that can be identified by its reaction to acid is calcite.
Explanation:
A mineral is any of a class of substances occurring in nature, usually comprising inorganic substances, as quartz or feldspar, of definite chemical composition ad usually of definite crystal structure but sometimes also including rocks formed by these substances as well as certain natural products of organic origin, as asphalt or coal.
Calcite is one of the commonest minerals, calcium carbonate, CaCO3, found in a great variety of crystalline forms: a major constituent of limestone, marble, and chalk; calcspar.
Minerals are where chemistry and geology intersect. A mineral is a naturally occurring substance that has a defined chemical formula and crystal structure. Chemists call these pure substances - often chemists and geologists have different names for the same thing - For instance the mineral gypsum is known to the chemist as calcium sulfate.
Different minerals differ by having a different chemical formula (like diamond and corundum), and/or by having a different crystal structure (like diamond and graphite). All samples of a specific mineral will form the same shaped crystals and be composed of the same elements in the same proportions regardless of where the sample was collected.

How do climate and landforms determine the
characteristics of a biome? (25 points)
To write a good essay whose theme is biomes and their characteristics, it is necessary to pay attention to the structure of the text, with well-defined and organized ideas, developed from a research in reliable sources.
How does climate and landforms determine the characteristics of a biome?A biome corresponds to an ecosystem and habitat that share the same characteristics, such as temperature and precipitation levels, which are relevant factors for identifying the type of biome.
Climate is the key abiotic factor for determining the conditions and type of terrestrial biome.
To complement your writing, you can give examples of different biomes and their characteristics, researching information on climate, relief, precipitation levels, to increase understanding of the topic and reliability to your ideas.
Therefore, the climate and the landforms determine the characteristics of a biome by the conditions that the landscape will have, since the intensity of the arrival of light and the rains provide the conditions for photosynthesis, being essential characteristics for the development of certain types of vegetation and of life.

Discuss the fundamental epistemological debates concerning on the source of human knowledge
Answer:
Epistemology (the philosophy of knowledge) breaks down into two categories:
A true belief.
A justified true belief.
The first has been referred to in many different ways over the millennia: dogma or axiom being ones that most people recognize.
The second form of knowledge exposes the basic problem; the infinite regress. A chain of justifications must either be infinite (and, it cannot be infinite, for obvious reasons), or have a starting point that does not require justification, which gets us the first form.
Different philosophers have attempted to solve the infinite regression problem in order to do away with the first form of knowledge (mostly because they just have a visceral dislike of it: it smacks of religion).
1. (a) Define the term internal trade.
International trade is the term used to describe the transfer of goods and services between nations. It refers to the export and import of commodities and services, to put it simply. While imports are sales of goods and services into the nation, exports are sales of products and services to other nations. No import or customs tax is imposed on this transaction since the products and services are produced and used domestically. Wholesale trade and retail trade are the two subcategories of internal commerce. Adam Smith and David Ricardo, political economists, were early to understand the significance of international commerce. Some claim, however, that commerce between nations may really be detrimental to smaller nations, which has a greater negative impact on the global economy. Trade across borders involves more than simply consumer items. It involves moving raw commodities from areas where they are abundant to areas where they are scarce. As a shipping broker, my most recent ship serves as a good illustration of this. In West Africa, manganese ore will be loaded before traveling to Western India. They anticipate that the US wheat production may be lower this year. In order to react, World Trade ships from countries like Russia and Argentina that are experiencing a prosperous year. This may radically alter the next year. It maintains price stability and distributes resources only according to quality, supply, and demand. Everyone wins, everyone wins.

2cm==30
A fraction scale is depicts a portion of an object or geographical feature on a map. While a linear scale has equal divisions for equal values.
What is the fraction scale of 2cm = 30Km?1 km = 1000 m, and 1 m = 100 cm.
=> 1 km = 1000 × 100 cm = 100000 cm
=> 10 km = 10 × 100000 cm = 1000000 cm
From the question, 2cm represents 30Km, Hence,
2cm represents 3,000,000 on ground
=> 1 cm represents (3,000,000 / 2) cm on ground
or 1cm represents 1,500,000cm on the ground.
Thus, the The representative fraction of the scale is 1 : 1,500,000.
This means that 1 cm on map represents 1,500,000 cm on ground.

what is the correct formula to calculate the discharge of rivers?
Answer:
CORRECT FORMULA TO CALCULATE THE DISCHARGE OF RIVERS IS ;
Discharge = V×D×WPLEASE VOTE ME WITH 5 STARS...:)
The following is the proper formula for calculating the discharge of rivers:
Discharge = V x D x W
Discharge uses units of feet3/sec or cubic ft per second if length and duration are measured in feet and seconds, respectively. The cross-sectional area is calculated as Depth times Width.
What is river discharge?The amount of water flowing through a river channel is known as the river discharge. In cubic meters per second, this is the total amount of water flowing through the channel at any particular time (cumecs).
A drainage basin's discharge is influenced by storage, evapotranspiration, and precipitation data. Precipitation plus evapotranspiration plus/minus changes in storage equals drainage basin discharge.
Discharge can be shown using hydrographs. These can be used to illustrate how annual flow patterns relate to the climate.
